In the mountain ranges of Colorado, USA, the ‘Hard Rock 100mile Race’ with an actual distance of 160km and an accumulated height of 10,000 meters is one of the ultimate mountain races in the world. ‘Kroger’s Canteen’ is an aid station on a tiny ledge and an oasis-like place for the Hard Rock Race participants where they get provided with water and food. The race continues as the story of the staff that heads toward the mountain with heavy backpacks on their back in order to put together Kroger’s Canteen.
